The aim of this paper is to explore the potential capabilities nonlinear projectors represent integrated behaviour products when manufacturing involves several plants inside a typical facility heavy industry. interest focused in supervision production able identify sudden failures or infrastructure attacks discovered from process perspective. In analysis, not only feasibility but also computati...

Considering the head and tail deformation phenomenon in slab rolling process, this paper studies online width adjustment control problem of continuous casting based on digital twin framework. First, material mechanical properties, geometric model boundary conditions are given to establish process by using rigid-viscoplastic finite element method. Second, rolled piece is mainly reflected shape p...

quality inspection is an indispensable part of modern industrial manufacturing. steel as a major industry requires constant surveillance and supervision through its various stages of production. continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. once the slab is released from the casting unit, th...

Problem statement. Development of an effective technology for the skin-rolling will allow production hot-rolled sheet products with quality indicators that meet requirements standards cold-rolled sheets. Consumers significant economic benefits be able to use relatively inexpensive sheets instead expensive The purpose article: establishment effect various technological schemes hot rolled fine an...

Based on the analysis of influence roll vibration elastoplastic deformation state a workpiece in rolling process, dynamic force model with hysteresis effect is established. Taking parameters 1780 mm hot mill as an example, we analyzed between and displacement by varying speed, radius, entry thickness, front tension, back strip width. Under considering nonlinear backup work rolls well structural...

Rolling bearing is main part of rotary machine. It is frail section of rotary machine. Its running status affects entire mechanical equipment system performance directly. Vibration acceleration signals of the third finishing mill of Anshan Steel and Iron Group wire plant were collected in this paper. Fourier analysis, power spectrum analysis and wavelet transform were made on collected signals....
